Abstract

The invention provides an essential oil microcapsule, a preparation method and application of the essential oil microcapsule in a humidifier, wherein the essential oil microcapsule comprises a capsulewall and a capsule core filled in the capsule wall, and the capsule core comprises oregano essential oil and limonene. According to the invention, the capsule wall isolates the contact between the capsule core and the outside, so that the volatilization speed of the essential oil is effectively reduced, the effective time of the essential oil is prolonged, and the replacement frequency of the essential oil microcapsules is reduced; and the two essential oils are matched with each other, so that the antibacterial ability of the essential oil microcapsule is improved, and the effective antibacterial time of the essential oil microcapsule is prolonged to a certain extent.

Description

technical field [0001] The invention relates to the technical field of microcapsules, in particular to an essential oil microcapsule, a preparation method and its application in a humidifier. Background technique [0002] Humidifiers, as a small household appliance that daily increases indoor air humidity, have become more and more popular. Humidifiers release a certain amount of water mist into the air to keep the indoor relative humidity at the most comfortable 40% to 60%, which greatly improves the comfort and health of people's living and working environments. However, the water tank and other components in the humidifier are in a humid state for a long time. If they are not cleaned regularly, various bacteria will breed, which will have an adverse effect on human health. [0003] At present, fungicides are mainly added to the water tank of the humidifier to detoxify the water body. However, the commonly used fungicides are artificially synthesized chemical substances, ...
